Reading standard registers on the QT2025C before its firmware has
booted may cause the boot process to fail. Therefore, follow the
recommended reset sequence before reading its id registers. Either
order works for the QT2022C2, so don't differentiate.

Falcon can generate events for LASI interrupts from the PHY, but in
practice we have never implemented this in reference designs. Instead
we have polled, inserted the appropriate events, and then handled the
events later. This is a waste of time and code.
Instead, make PHY poll functions update the link state synchronously
and report whether it changed. We can still make use of the LASI
registers as a shortcut on the SFT9001.

Put all static information in struct falcon_board_type and replace it
with a pointer in struct falcon_board. Simplify probing aocordingly.

Rename struct efx_board to struct falcon_board.
Introduce and use inline function to look up board info from struct
efx_nic, in preparation for moving it.
Move board init and fini calls into NIC probe and remove functions.

efx_board::init_leds was introduced as a second stage of
initialisation because of the inter-dependency between the board and
PHY. We want to move board initialisation into NIC probing, which is
too early to use MDIO, so SFN4111T initialisation also needs to be
split.

Only some PHYs have firmware support for a LED blink mode, so we
currently blink the others in a timer function. Since all PHYs have
simple on and off modes, we don't gain anything by using multiple
blink implementations. Also, since we have a process context there
is no need to use a timer.

The 'XFP' driver is really a driver for the QT2022C2 and QT2025C PHYs,
covering both more and less than XFP. Rename its functions and
constants to reflect reality and to reduce namespace pollution when
sfc is a built-in driver.
